Voltage Translator Board

The Voltage Translator Board is an accessory board that performs level conversion of a 5V interface (I/O24 or microcontroller) to a 3V3 or lower interface. You can connect this board to a single port on the existing I/O 24 Range.

The board consists of two 74LVC4245 Bus Transceivers that are used for the level conversion.
Each device is configured for a set level conversion of either 5V to 3V3 or 3V3 to 5V for a single 8-bit port

FEATURES:

• 2 X 74LVC4245 Bus Transceivers for voltage translation
• 2 x I/O ports matching configuration of I/O 24
• Selectable jumper pins for the direction of voltage translation
• Onboard Voltage Regulator to supply the 3V3 side
• Easy connection to the I/O port via a 10-way box header that suits a standard IDC connector
• 72mm standard width for DIN Rail Mounting Modules
• Compact measurements 40 x 72 x 11mm
• RoHS

• IGND: Ground current ‐100 0 mA
• Tstg: Storage temperature ‐65 +150 C
• Plot: Power dissipation Tamb = ‐40 C to +125 C ‐ 500 mW

NOTE: Care will need to be taken when connecting this device to the USB
I/O 24 as you may exceed the maximum current draw allowed via the USB
specifications.

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angle and display monitor.
